I just saw this on a newegg review.
"Positioning of side vents makes it too narrow to fit a 25mm thick fan with a "tower" style CPU cooler (like a Hyper 212+/EVO). I will try a 15mm thick fan."
So it had me worried.
Hmm. Maybe the poster of the review is right. From the pictures of the case at the egg, it doesn't look like the side vents take up much room at all, so that's why I said it should fit, but you might want to call Corsair before you buy, just to be sure.
